I am working on a high-performance switching system. I the old ones there was no big issue in just touching a gate with an oscilloscope probe, but this time I have high voltage and very short (5nsec) rise/fall time, so I have to think through test points.
I would go for SMA and then connect it with a coax to the scope, but I have no room for that.
So the question is, what are the recommendations for the smallest possible test points to measure fast switching power transistors behavior. Maybe some special probes can be used. What did you fellas do in the past?
Upd: due to the relatively high voltage and small size of the product, i really don't want to touch it while it is working. It has to be something that the probe is nicely attached to it. Additionally the ground of the probe should be very short, ideally it would even be a nice differential probe (although at this point i am most interested in preparing everything in layout).
